I think this is dreadful - making imaginative games, stories, role play, often (tho not always) applying the 'intellectual' things you have learnt about or experienced to the game, is a huge skill and something I love my DCs doing, be it a sophisticated piece of kit or a bit of old hoof they found in the garden.
Likewise enjoying the pleasure of textures and creativity with playdoh (would it be different it is marked 'clay for 5-10s on the box?), sand etc is a fantastic activity and one to maintain. And relaxing with an easy, trusted favourite eg Charlie and Lola etc - great. Sometimes it is nice to switch off and/ or not be getting endless cerebral development from everything, so what if it is slightly dumbing down? it's like when I read vacuous celebrity magazines 
I am thrilled my similar aged DD does all these still - she is at school all day learning the key skills, I think it's great and shows appetite for life and learning to continue to find new things you can do with what you already have and think you know. Appreciate that sounds a bit earnest and hippy but I would be positively sad if I thought she responded to weird-looking-but-that's-a-different-point monster high dolls and drawing and nothing much else.
There is some stat about the age at which girls give up actually playing with toys, because they move onto their focus being on makeup, hair, boys etc, an age getting increasingly younger. This makes me very chuffed that my DCs value the feelings and sensations they get from play, whatever it is with. It's kids who are easily 'bored' and need to be staring vacantly into iPads all the time that are most worrying not kids who play with the 'wrong' things.
