PMC kernel issues: less noises but less (=worse) color

Hi.

I tested "Idea" scene (Octanebench v2.17) using OR demo v2.24... I detected many strong noises at lamp showed due to be very bright but less noises = better at lamp hidden.

See differences between 3 images
Lamp showed:
pmc test - light yellow showed.PNG
it's normal but abnormally more noises at 1500 S/px.

Lamp hidden:
pmc test - light yellow hidden.PNG
less yellow is issue but goodly less noises despite same S/px.

Lamp hidden with fake shadows (=fake caustics):
pmc test - light yellow hidden with fake caustics.PNG
it's normal but 1st image is differents to last image because true caustics (= fake shadows disabled) is much more realism than fake caustics

-camera settings with linear preset except exposure 1.850, gamma 2.200 and vignetting 0.000 but look specular and diffuse materials and PMC settings - look 3 images

I wait you'll fix these issues for PMC kernel.

NOTE: I tested Path Tracing and this kernel hasn't any issue despite noises and 10k samples/px. ;)

If V3 fixes these issues then I'll pay 416euro by OR v2+plugin v2 for Blender and later I will upgrade FREE to v3. Upgrade of v3 should be free because PMC kernel of v2.x has errors.

I'll buy OR v2.x stand+plugin for Blender by 416 euro soon
Sorry, I've bought standalone only (not plugin) because my father said me 416 euro is expensive. ;) But I'll upgrade to standalone v3 on this month or next month. :)

I tried to new demo v3.00 and I got better performance by 1.7x than full version of v2.25 at PMC kernel :D but unfortunately v3.00 doesn't reduce strong noises colored yet at idea showed!?!
