LightRoom 6: Inaccurate Develop Preview Colour Mapping for ColorChecker Chart

A TIFF colour test chart (with an embedded sRGB profile) was created using the exact colours listed in https://en.wikipedia.org/wiki/ColorCh.... The colours so created were then verified (via the Color Picker tool) in the Paint.net Windows utility program.

I noticed inconsistent colour display in the LR6 Develop module. For example, compare the colours between the Navigator and Preview windows in the attached screenshot. A similar discrepancy is noticed when displaying the image in fullscreen mode. To my eyes, the preview image is over-saturated as well as colour-shifted.

I would appreciate it if someone else could verify these findings.

This might be related to http://feedback.photoshop.com/photosh..., which will be fixed in the coming dot release.

The navigator view is still rendered through the CPU path (not GPU accelerated), while the main loupe view is.

Thanks Simon. I did try toggling the GPU enable preference setting to no effect. I suspect that this may be related to colour space mapping.

Would it be possible for you to reproduce my results using the test chart at the link previously provided?

I exited LR and relaunched the program. To my surprise the Develop Preview colour mapping now seems to be okay.

On my first attempt, I do recall using the Soft Proofing feature but have no idea what lead to the issue that I previously reported.
