I think there's a balance. It is very important that children learn life skills like making their lunch, bedmaking, how dirty laundry goes from the bedroom floor to become clean laundry in the drawer. It sounds like the OP's dd likes making her lunch - and maybe she's more likely to eat it if it's something she's chosen and made herself - and emptying and wiping her lunchbag isn't a terribly onerous task. Emptying the dishwasher is a bigger job, and not one that my dses did until they were older, but if it works for the OP and for her dd, then that's fair enough - as is putting on the occasional load of washing (not every load, or even half the loads, but once or twice a week, maybe). I remember how much I loved being allowed to use the proper soap powder to wash my dolls' clothes, and might have enjoyed doing more, if mum had let me.
I do also think it is a good idea for children to help with household tasks - the boys have been helping sort out the ironing from the non-ironing, and then sorting the non ironing and folding it, for years. They take turns to empty the dishwasher, and to be responsible for cleaning their bathroom and for emptying the bins and the recycling, and putting the wheelie bins out for the bin men. Doing this is partly about earning pocket money.
We didn't start them doing these tasks as early as the OP has with her dd, but she knows her dd better than we all do, and if she's happy doing the jobs and it's not a burden to her, then I don't see a big problem.
As our boys have grown up, we've let them do more in the kitchen, and now they are all capable of getting themselves a basic meal - pasta with tuna mayo, or marmite pasta with a poached egg, spaghetti bolognese etc, and I am teaching them the basics of cookery - how to chop an onion, what recipe terms actually mean - so they can feed themselves when they leave home. They also know how to use the washing machine, so hopefully they will stay clean.
When my father went to teacher training college, one of his fellow students was a welsh lad whose mum had done literally everything for him - told him when to change his socks/shirt/undies etc, when to have a bath - and he had no idea at all how to care for himself. In the end, alerted by the smell, Dad and his friends questioned this chap and found out he hadn't bathed or changed his clothes since starting at college - and they had to educate him on how to care for his own hygiene needs - they made him a chart to follow, so he could see when he needed a bath or a wash, and when to put on a clean shirt etc.
