I think this is very likely. Keeping in mind this is a Linux-based system, it makes sense that they have to page in the apps when they are first launched. Once paged in, they likely transition faster until they have to be paged out due to use of other apps. I have no way of knowing how much memory they are using, but Linux is pretty efficient, so they may have felt they don't need a lot.
Makes sense, would explain why you can measure a delay in many videos and in my car while it didn't seem to be there in some and for you. You should expect two cars to perform near identical so the load times should be very similar between two cars.
On another note I think I need to apologise for my previous message in this thread when you said your experience did not align with mine. I took it to mean your experience was that there were no delays and not that you actually could time it to be instant. If that sentence doesn't make sense please tell me but it is the best I can do in English right now with my brain fatigue.
The trouble with any sort of discussion like this is that it is hard to know what someone have measured and what they experience. I've had discussions where people claim their Model 3s are as quiet as their BMWs, or that the i4 isn't that much more quiet than the Model 3. While it is hard to measure how we humans will experience the noises (and it is individual how we hear different frequencies) we can at least measure it and say that the i4 is quieter.
Contrary to what your perception of me might be I do try to stick to facts when it comes to things like this, if I say there's a delay I want to be able to show there is one on a recording (like the linked YouTube videos)
While on the subject I might as well apologise for being a bit of a negative nancy here on the forum, I am realising I've been heavily skewed towards the negative lately. Just in that kind of place psychologically right now, but focusing on the negatives isn't really the right way to go about it, should focus on the positive things instead.
