Your workflow does not sound very reliable. I'm not that convinced about your way of making TIFFs. This won't be the case when you have real 10bit panel and 10bit preview. It may even look better than real 10bit file. If gradient looks very good on 8bit preview it most likely uses dithering. Also- grey color changes due to dithering. Zoom in AE to 400% and you will see pattern easily. If some tool uses dithering you may be fooled, so watch for it. Ordered dithering is compression resistant but it also creates distinct pattern. Looks like ffmpeg now does it by default (ffmbc did for long time). You have to be watching for dithering also. Metadata in this case is meaningless as you don't know what data went through during whole conversion.ġ0bit h264, dithered 8bit h264 (ffmpeg does it by default now), pure 8bit h264 (check original 16bit TIFF) This is the way to tell if your workflow keeps 10bit. You will see straight away if file is 8bit or 10bit.
Do crazy curve filter (you can do even 2 instances which pushes things a lot) on both (source and you exported file) and compare. Convert this h264 in TMPEGenc and load your final 10bit back to AE set to 16bit mode. If not possible then export v210 uncompresed out of AE and convert to 10bit h264 in ffmpeg- use very high bitrate (e.g. AE), export the same format as you testing. You can't be sure just based on this at all.

Regardless all of this, you also needs to know that your software actually preserves 10bit (or whatever) depth and does not use eg. This has been reported as bug and Adobe analysed it, but never gave me an answer. AME RGB 12bit mode is actually also 10bit.
