I double-checked internally and there is a known issue with splash screen on native HDMI as well. The issue was found during the release testing for 7.2.0. Though the issue wasn’t deemed critical and the release happened with the issue present.
For now there is no known fixes or workarounds. Our team is already aware of the issue. They will need to investigate and work on a fix in the future.
