Description

The issue is that on iOS devices textures are displaying significantly darker than expected.

I did a color calibration with my monitor to get a more accurate representation of the texture. I set the texture the texture group UI, and those did not change the issue. A workaround is available by unchecking the sRGB box in the texture settings, as well as changing the compression settings to UserInterface2D. This makes the texture much brighter and shows up less dark on the iOS device.

Regression? (yes)
Worked in (4.14.3) CL 3249277
Broken in (4.15.P2) CL 3269047

Only affects iOS?
Yes, Issue was tested on Android and does not occur in 4.15.P2 or 4.14.3

Steps to Reproduce
  1. Prerequisite: Make sure You are able to deploy to iOS Devices
  2. Create a new Blank Project > No starter Content Needed
  3. Import WoodernBG.TGA
  4. Create a new Widget BP > Name "Test" > Open Widget
  5. Add Image to Canvas Panel > Set Anchors to all corners > set all offsets to 0
  6. Set all Alignments to 0
  7. Open Level BP
  8. Add Widget to Viewport upon Begin play
  9. Let Project Package on iOS Decvice
  10. PIE and Open Project on Phone

Result: Texture on iOS Device is much Darker (or Redder in this specific case) than what is on your Editor Screen

Expected: The colors of the texture should match (as close as possible)
