In the meantime I received this reply from AMD based on photos and description
" Based on your inquiry, I understand that you bought an AMD Ryzen 7700 processor, but it looks different from the ones shown in tests and pictures online.
I would like to inform you that this is a new design CPU.
In the new design the capacitors are not present in the upper half portion of the substrate outside the IHS.
As per our record shows that AMD Ryzen 7 7700 with serial number # 9AKB077X40467 is OEM/tray unit and it is sold by AMD as an OEM/System integrator product, which are sold with the express purpose to be integrated and sold as complete system only. "
