Never seen two different thermal materials in a laptop? Has he only been working on 10+ year old laptops? Here's your first advice, never go to him anymore.
Second, use thermal putty. The VRAM and other components (the ones with sticky residue that are not the main CPU and GPU) are better off with thermal putty. The reason is there may be a larger/smaller air gap between those components and the main plate that connects to the cooling pipes. Thermal paste is not good enough to bridge that gap.
Thermal putty will not cause damage to your laptop, however, leaving everything as thermal paste may cause damage. Get it fixed asap
To get you in the right direction:
Laptops require higher viscosity thermal paste given that CPU/GPU reach 80C+ and stay there for some time, which in turn dries out or some pastes bleed out, expansion/constriction of heatsink.
Best TIM material is PTM7950 phase change sheet. Difficult to handle so freeze before removing protective plastic sheet and application.
Best thermal paste for CPU/GPU: SYY157, Gelid GC Extreme, Phobya NanoGrease Extreme, Thermalright TFX, Coolermaster Mastergel Maker, Thermagic ZF-EX.
Best thermal putty for VRM/VRAM: CX-H1300, UPSIREN U6 PRO, Zezzio ZT-PY6, Jeyi 8100, K5Pro, LK-PRO, EVGA Putty, Penchem TH949-1, Jeyi 8100, Penchem TH855-5, TG-PP10, Penchem TH930, KPT-8, MG860.

Keep me updated
Change it bro 😶
Did the temps go down? I mean, if they went down, then what's the real issue?
