I can't confirm: Tiffs with AdobeRGB embedded profiles work fine for me (Beta 5):
- they look different with/without option.
- JPEG and TIFF versions look exactly the same (and as they should be).

-> moved to 'New' (waiting for more confirmation).

I've found the problem - if tiff file is 8bit-per-channel image and HAS ONE alpha channel it's icc looks incorrect.
if tiff file is 8bit-per-channel image and hasn't alpha channel or has two additional channels it's icc works well in xnview.
if tiff file is 16bit-per-channel image icc doesn't work at all in xnview.

here is link to archive with some images.
I can send you these files by email, if it is more convenient.

I confirm both those situations with my own images...

problem with icc in 8bit-per-channel tiff files is fixed. I think so:)

Sorry, I couldn't find any other related topic. Is this still valid? Currently Xnview doesn't display correctly 16bit-tiff-files with embedded icc-profiles. I'm using PS and Lightroom for photography and both use 16bit-tiff with Prophoto.

Thanks

Yes, currently ICC works only on 8bits files
