Yes, I've been playing with these markers yesterday and it seems you're right:

"The color space to be used is YCbCr as defined by CCIR 601 (256 levels). The
RGB
components calculated by linear conversion from YCbCr shall not be gamma
corrected
(gamma = 1.0). If only one component is used, that component shall be Y."
>From the JFIF spec.

We need something on image/jpeg caps to detect and prevent that.
