Can a domains TLD be considered as part of a trademark?

I have registered a domain, let's say it's "acme.io", and am planning on using it for an online booking system.

After registering the domain I found out that in the EU a trademark exists for the word "acme" with the following classes;

Class 9: Computer software for use in designing, developing, creating, publishing and printing books.

Class 38: Communication services; electronic transmission of data, messages, images and documents.

Class 40: Printing services and consulting services in the printing industry; custom production, setting, printing, binding and finishing of books.

Class 42: Computer software design and consulting services; formatting, graphics and textual design services in the publishing and printing industries; design of books to custom; application service provider services; providing temporary use of on-line non-downloadable software in the field of designing, formatting, printing and creating books; provision of technical assistance and support services (including by telephone) in the fields of designing, formatting, printing and creating books, and the use of software therefor; operation, maintenance and updating of Internet websites and website portals for use by others; licensing of computer software and other intellectual property or proprietary materials.

I'm not too worried about classes 9, 40 & 42 as they all have a focus on the book publishing/design industry.

It's class 38 that is very vague, and a bit of a worry.

Can I still get away with branding myself as "acme.io"?

Can the domain name, regardless of TLD be claimed back by the "acme" trademark owner?
