How to reproduce:
1. Open the attached project (1186265test.zip)
2. Build and run the project (make sure Development Build is enabled)
3. After the splash screen in the Player ends, go into the Editor -> Window -> Analysis -> Memory Profiler
4. Switch from 'Editor' to the Player that is currently running and take a snapshot
5. Open the snapshot and sort the memory table by 'OwnedSize'
6. Notice that 'splash_logo' is high on the list (around ~150 KB owned size)

Expected result: Splash screen resources are not present in memory
Actual result: Splash screen resources are kept in memory

Reproducible with: 2018.4.17f1, 2019.3.1f1, 2020.1.0a23
Could not test with earlier versions due to Memory Profiler either throwing errors or crashing Unity altogether

Note:
- Seems to be a regression from https://fogbugz.unity3d.com/f/cases/960554, but the bug was present where I could test with this method
