[SystemSettings] TEXTUREGROUP_ not working ?

I tried to limit my texture resolutions by adding TEXTUREGROUP settings into DefaultEngine.ini (copied from Texture Support and Settings | Unreal Engine Documentation).

[SystemSettings]
TEXTUREGROUP_Character=(MinLODSize=256,MaxLODSize=1024,LODBias=0)
TEXTUREGROUP_CharacterNormalMap=(MinLODSize=256,MaxLODSize=1024,LODBias=0)
TEXTUREGROUP_CharacterSpecular=(MinLODSize=256,MaxLODSize=1024,LODBias=0)
TEXTUREGROUP_Cinematic=(MinLODSize=256,MaxLODSize=4096,LODBias=0)
TEXTUREGROUP_Effects=(MinLODSize=128,MaxLODSize=512,LODBias=1)
TEXTUREGROUP_Lightmap=(MinLODSize=512,MaxLODSize=4096,LODBias=0)
TEXTUREGROUP_Shadowmap=(MinLODSize=512,MaxLODSize=4096,LODBias=0,NumStreamedMips=3)
TEXTUREGROUP_RenderTarget=(MinLODSize=1,MaxLODSize=4096,LODBias=0)
TEXTUREGROUP_Skybox=(MinLODSize=512,MaxLODSize=2048,LODBias=0)
TEXTUREGROUP_UI=(MinLODSize=512,MaxLODSize=1024,LODBias=1)
TEXTUREGROUP_Vehicle=(MinLODSize=512,MaxLODSize=1024,LODBias=0)
TEXTUREGROUP_VehicleNormalMap=(MinLODSize=512,MaxLODSize=1024,LODBias=0)
TEXTUREGROUP_VehicleSpecular=(MinLODSize=512,MaxLODSize=1024,LODBias=0)
TEXTUREGROUP_Weapon=(MinLODSize=256,MaxLODSize=1024,LODBias=0)
TEXTUREGROUP_WeaponNormalMap=(MinLODSize=256,MaxLODSize=1024,LODBias=0)
TEXTUREGROUP_WeaponSpecular=(MinLODSize=256,MaxLODSize=1024,LODBias=0)
TEXTUREGROUP_World=(MinLODSize=256,MaxLODSize=1024,LODBias=1)
TEXTUREGROUP_WorldNormalMap=(MinLODSize=256,MaxLODSize=1024,LODBias=1)
TEXTUREGROUP_WorldSpecular=(MinLODSize=256,MaxLODSize=1024,LODBias=1)
TEXTUREGROUP_MobileFlattened=(MinLODSize=8,MaxLODSize=256,LODBias=0)
r.setres=1024x768

This didn’t work at all. I opened the level statistic page, open the texture windows, all showed that max ingame resolution still 4k.

Did I do anything wrong or this is a bug ?

The settings moved to DefaultDeviceProfiles.ini since like 4.8, the document is just terribly outdate.
