After a thorough investigation, we've resolved the issue regarding the splash screen logo appearing despite the "Show splash screen logo" being disabled. Our findings indicate that the reported discrepancy in size was closer to 100KB, not the initially stated 2.7MB.
Upon conducting further tests, we confirmed a difference of approximately 50-100KB between builds with and without the logo. Additionally, we verified that the logo undergoes compression during the build process, utilizing DXT5.
We want to clarify that the reported sizes in the build report reflect uncompressed usage rather than the final size due to collective asset compression. Therefore, the discrepancy in reported sizes cannot accurately represent individual content within the archive file.
As a result, we've decided to close this bug as "won't fix"
We understand the importance of accurate build size information for fine-tuning your projects, and apologize for any inconvenience caused by this limitation of the current system.
