Thank you. Very interesting. My subjective quick ranking:
Image 3/5: LMC 8.4 with Antykat [6.1 MiB]
Image 4/5: LMC 8.4 Leica Mode [6.0 MiB]
Image 5/5: LMC 8.4 HDR+ net [6.2 MiB]
Image 1/5: BSG 8.1 with MK V7.3.5 [4.3 MiB]
Image 2/5: BSG 8.7 with NF2.5 for 8.6 [3.1 MiB]

Currently I have no time but including a MIUI Cam pic and maybe from some DSLR (Canon) would be very interesting. Seems quality settings (JPG file size) also play a role, as BSG seems to compress more.

It's rom related problem. The xml was created on MIUI and 16:9 photos works properly.
It is indeed ROM related - I talked to a guy who is a serial flasher and according to him all the OSS based Android 13 ROMs on the X3 Pro suffer from this "washed out photos" phenomenon (it affects only displaying the photos on the phone, they look normal on Google Photos on the web).

So in short it's not a Camera issue it's a Display issue that the Colors aren't overly bright on AOSP based ROMs compared to MIUI.
Depending on the ROM there should be display Color correction options which might increase Saturation and others.

I would like to find the best option to "scan" pages/documents/book-pages in an optimized format and if possible create a hOCR-PDF file (Original image with underlying hidden OCR-text) directly on the phone (vayu). Interesting are the following features:
Contrast/Sharpness
Text / Image separate optimization
Binarization (B/W)
Auto-Crop
Border/Blob Removal
Noise/Finger Removal
90° Rotate
Deskewing/Auto-Rotate
De-Trapezoid
Unbend
Dewarping (thick book pages)
OCR (European languages)


Since Google Camera update 7.2 (2019) at least on Pixel smartphones Google Lens visual recognition is integrated offering "Scan document" when such an object is recognized with feature to adjust the corners (including manually). Also the options "Share PDF" and "Share Image" is offered.
MIUI/ANX-Cam has a document mode which works well except for book pages curvatures, I have tested many Apps regarding optimized Document-Picture features (including for thick Books) and found vFlat an interesting app for intelligent "flattening" by deep learning of a page/document/book-page and also a surprisingly good OCR in multiple languages (limited daily free credit).
Since I have no Pixel device to check I would like to ask how good GCam Lens recognition is currently and if saving/sharing as PDF means in the hOCR-PDF Format?
Is there any GCam for vayu (or other App/Combo) supporting "Scan Document" and hOCR-PDF?

have you tried Microsoft Lens?
By your suggestion I tried it for the first time, thank you for the suggestion. I was expecting I need an MS Account and as well Online-Connection but surprisingly the App works without and by selection creates hOCR-PDF. The other options are saving image to Gallery and by MS-Login Word, PowerPoint, OneDrive, OneNote.
The pre OCR image optimization seems not as sophisticated (or AI assisted) as seen elsewhere but the offline OCR is certainly very good for an Android App. Only flaws I noticed are missing spaces and no recognition of lists/tables. The creation of documents/books seems to be limited to 100 pages according to an App-Review, not sure if for performance-limits or other reasons, but this seems ok to me.
So maybe "scanning" with ANX-Cam or vFlat and then OCR the images by MS Lens is a good process on the SmartPhone, need to try that. For big projects probably it is better to do the OCR on the PC.

Has v.8.4 ultrawide option? In a previous version there was 0.6x selection, now there is only 1x and 2x.

Use PhotoScan by Google. I have not tried unbend, glare works wonderfully. Even for posters on the wall.

Has someone "Google Lens suggestions" for scanning documents (autocrop, enhance, etc.) working in a GCam? Despite this option activated in LMC and MGC the Cam seems to never recognize documents?
