In a screenshot it’s ‘Play’ + katakana. In some languages I checked on Wikipedia it’s always ‘Google play’ or partially or completely translated, in korean it’s completely in hieroglyphics, in chinese it’s used both ways (with play staying in english), in japanese it’s called entirely in english:

Google Play（グーグル プレイ）は、Googleによって提供される、主にAndroid及びChromeOS（2016年4月以降）向けデジタルコンテンツ（アプリケーション・映画・音楽・書籍など）の配信サービス[1]。2012年3月6日にGoogleは「Android Market」を「Google Play」に改名し、「Google Play ブックス」「Google Play Music」といったサービスも合わせて誕生した[1].

Brand managers influence wikipedia too, some even create their own pages and update them. It makes me think it’s a marketing thing - a dedicated department thinking if they can translate these words and if it makes the brand look better to the public. Like that script in burmese (Myanmar) it has it all translated into their language: https://my.m.wikipedia.org/wiki/ဂူဂယ်_ပလေး
