Always On Display During Activities Never Dimming

Just upgraded from a 955 to a 965 for the obvious reason of the screen.  I have my settings to have Always on Display always on during activities.  I don't mind charging more often for this.  But what I also noticed is that similar in it's home state, the watch still dims/times out during a run.  The gesture setting is still on, but I really hate the gesture setting as I run with my watch on the inside of the wrist not on top and even if I did wear it on top gesturing to better see the screen to check data is just annoying.  

I understand why this is case, to save battery life, but is there an option to always have the brightest display and it never time out while in an activity?  if not, I might have to go back to my 955 as this doesn't make sense to me and is a bit annoying. 

Thanks all!
