mygsm.me has black N920C 64GB in stock, link http://www.mygsm.me/Samsung-Galaxy-Note-5-64gb-price-dubai.html
I ordered one 2 weeks ago and it was delivered in 3 days.
Samsung has started production of Apples next processor using 14 nm technology.

So the Exynos processor for the Note 5 will probably use 14 nm technology.
Snapdragon 810 is using 20 nm technology.
It's possible to get pretty accurate colors by setting "Screen mode" to Basic and disable "Auto adjust screen tone"
in "Display and wallpaper" settings.
It seems Samsung has renamed Exynos 5433 to Exynos 7 and has A57/A53 according to the link

Yellow effect is the same as yellowish white ?
When reviewers say measured color accuracy is excellent, it usually includes white.
So it's a bit confusing.
Here is another review that says colors are excellent when using basic mode.
So maybe there are differences between each Note 4 or the other screens you use are less accurate.

It makes it possible to have two apps on the screen at the same time.
I think it is more advanced than Screen Adjuster after reading his Twitter..
But you could ask him if DisplayExpert is better at fixing yellow tint than Screen Adjuster.
Here is a link to his Twitter: https://twitter.com/supercurio
Supercurio is working on the app DisplayExpert which makes it possible to calibrate the screen.
He has it running on his S III according to his Twitter.
But the app is not finished yet.
