Improves the previous logic and makes it compatible with the new additions in 26.x, such as sRGB. This was previously broken as the focus was on existing features which could be tested without requiring a compiler to be installed. Incorrect understanding of how sRGB works with RGB and YCC/YUV formats also caused sRGB to be treated as RGB when I444 was selected. This should also now be fixed, hopefully permanently. Fixes #331
