From my readings (I can't find a research on this specific topic), the answer is more complex than yes or no.
Angiogenesis (creation of new capillaries) is related to anagen. So, you need blood flow to stimulate anagen but you need anagen to stimulate blood flow ( https://pubmed.ncbi.nlm.nih.gov/10771470/ )
This is why, when the hair is lost for many years (temple area), it is very very hard to get your hair back using medications.
You don't have a follicle there to stimulated angiogenesis.
By the other side, considering that the crown is not totally bald in many cases, you have some capillaries there to activate the anagen and activate the "virtuous" loop "anagen-agiogenesis".
When you transplant a follicle, I suppose it is a completely different story.
If you transplant both in crown and temples and presuming that you don't have hair for a very long period of time, angiogenesis will occur faster in temples, because there are more veins and arteries running in that area, so it is a "simple" process.
