I had just bought this model. It was faulty (the defect was not immediately visible). The extremely short return period for this matter did not allow me to exchange the device. I have now been waiting 20 days for a reply. I would advise you to be careful, if necessary buy another appliance or at least buy from a supplier who is better informed. After all, this is a working device.
Hello 😊. Yes, according to Lenovo this laptop is equipped with a "OGS, 10-point Multi-touch"-touchscreen.
Also, the details about the chipset and the GPU seem to be correct. You can take a look at the official Lenovo-specs on the following link: https://psref.lenovo.com/Detail/Yoga_Pro_7_14AHP9?M=83E30005MZ
