No, I haven't added any checks for that (and I'm not sure how the first one can be properly checked), so it's just an info bar. Which is, eventually, misleading.
UNET takes about a 1:10 on WebGPU and around a minute on CPU in one thread. VAE is 2 minutes on CPU and about 10 seconds on GPU. It should be because most GPU ops for VAE are already implemented but for UNET are not. So in the latter case browser is just tossing data from GPU to CPU and back on each step
