I just did a test of the different options & it seems the LinearGray gives a darker end image so I plan to give both options
As for size, here's a comparison. Taken from just the folder OEBPS/Images
Test ePub
start size: - - - - - - - 38.8MB - - Original size
no colorspace : - - 7.14MB - - 31.66MB Saved
LinearGray: - - - - - 6.75MB - - 390KB difference
Gray: - - - - - - - - - - 6.28MB - - 860KB difference
This book has 9 color images with 4 being mostly grey with a splash of color & the other 5 being full, rich, color
The text in images look much better with LinearGray, but the images, in general look overly dark
The image shades look more faithful to the original (IMO) with Gray but the text is less crisp in the images with text, still readable, but less crisp, even slightly less crisp than the color one with no colorspace adjustment
