Philips 65PML9008/12 Smart TV App Gallery Issues - Limited and Outdated

Good morning, Having recently acquired the Philips 65PML9008/12 Smart TV, I must say that I am quite dissatisfied with the presence of the app gallery. There are significant gaps in it, and it is not up to date. As a result of the absence of Android TV functionality, there is no provision for the addition of additional applications. Additional to that, it does not have access to the Play Store. Does this problem have a solution that can be found? Only YouTube, Netflix, and Amazon are accessible at this time; Puhu TV, Exxen, and Tod TV are not among the available services.
