Extraordinarily High Current Draw with Betaflight 4

Having heard burnt-motor stories with Betaflight 4, I've been delaying my update until now. Although defaults PIDs/filters fly good (only changes were my own rates), I found Betaflight 4 show extraordinarily high current draw on high throttle. Not just burst amp draw on sudden high-throttle situation but just high amp draw even at speed during funnels. I know my 2306 motors can handle 6S at 107A+ (for 4 together), but I can see why the burnt-motor concern. I have 2 different quads with very similar frame and powertrain yet my other one with Betaflight 3.5.0 would do just 88A. Actually both quads were doing 88A max when they were both running 3.5.0. The puzzling thing is that the Betaflight 4.0 one seems to fly perfectly fine no hint of high D or anything at high throttle yet the current draw is like 20% more on high throttle. Possibly because of that, voltage sag is higher and max Gs on hover-punchout is lower (8.2G vs 8.9G). This footage is a combination of the TTL setup (BF 4, 1st half, 0:00 - 1:32) and TTSH setup (BF 3.5.0, 2nd half, 1:33 - 2:53).
