It does not work perfectly actually.
Are you rooted?I've been able to easily install gcam for my Note 10S with the playstore app Gcamator
It use the BSG version and the appropriate xml config
Seem to works fine, I'm impressed by how photo quality is improved.

This is everything related to HDR in the developer settings..
