Yeah, but Havok has that precedent set. Unity doesn't, and since the price was so low previously, the ones with the splashscreen were the ones not willing to spend even a bit of money. Whether it's warranted or not, it goes give that impression of demo/low-budget/low(er)-effort.
I assume you haven't made "$200,000 USD or more in the last 12 months" from it, so you can relax.
