From the General AFV thread:
There's only one thickness type of base armour for production models. Any others are a result of test armour or optical illusions.
The MCO armour seems to use the base config.
I doubt Permali make all the armour. The contract is only for £15 million, which seems too little for nearly 600 vehicles. In an older blog post you mention that RUAG provided some armour but I can't find any other reference to this: https://below-the-turret-ring.blogspot.com/2017/08/which-new-ifv-for-czech-army.html
I wouldn't focus too much on the known armour configs anyway. Whenever the Army sends vehicles into a hostile environment they send out a Urgent Operational Requirement and buy a bunch of armour to bolt on (like Chobham Warrior). I'm expecting to see armour modules on the front glacis one day.
