After updating Photoshop Beta to version 27.10.0, all RGB PSD documents appear significantly brighter/overexposed.

The same PSD files display correctly in the current release version of Photoshop on the same Mac.

System

MacBook Pro 16-inch (2021)
Apple M1 Pro
16 GB RAM
macOS Tahoe 26.5.2

External monitor:

ASUS PA279 (4K via HDMI)

The issue occurs on both:

Built-in Liquid Retina XDR display
External ASUS PA279

Tests performed

Same PSD files display correctly in the release version of Photoshop.
Problem exists only in Photoshop Beta.
Proof Colors changes the rendering and makes the image appear much closer to the correct colors.
Disabling GPU Compositing does NOT solve the issue.
Disabling OpenCL does NOT solve the issue.
Disabling "Use Graphics Processor" completely fixes the problem.

Expected behavior

RGB documents should display identically to the release version of Photoshop with GPU acceleration enabled.

Actual behavior

With GPU enabled, RGB documents appear washed out / overexposed.

Inspiring

Actually, it makes it impossible to use! And it is less ‘overexposed’ or ‘brighter’, it is actually looking like a dust-filter is laid over an image eliminating the brilliance of colors and depth. I guess we have to wait for the next update which in beta’s case won’t be too long.
