Hello.
No, any changes to the experience yielded by a creature does not affect the "Raw XP" gained metric displayed on the tibia hunt analyzer window.

To confirm this, I hunted todays boosted creature, the renegade knight on 150% no prey. This is my hunt analyzer:
Session data: From 2024-06-04, 16:47:34 to 2024-06-04, 17:32:04
Session: 00:44h
Raw XP Gain: 838,525
XP Gain: 1,574,587
Killed Monsters:
299x cult believer
86x cult enforcer
176x renegade knight
181x vicious squire
82x vile grandmaster
As you can see, the XP gained is not the 150% experience of the raw exp (1,257,787.5).
